Horn.ell.a is the Horn Elliptic Aid software. With Horn.e.lla is possible to create in few minutes designs of several horn expansions as Hyperbolic, Tractrix, Spherical and Waveguide. The software is able to manage various parameters as frequency cut-off (minimum step= 1 Hz), axis samples number, flare constant, environment temperature and humidity, aperture angles, solid radiation angles and any size of horn throat, mouth and length. Horn.e.lla has some new features compared to similar products as the full 3D model, as environment information that permits to adapt working temperature and humidity, or as the aperture angles down to the horn section. This characteristic is useful in example to optimize horns with compression drivers, coupling horn profile with driver geometry and exit. Horn.e.lla develop profiles with a proprietary numerical algorithm that transforms the wave guide progression to obtain Circular or Pseudo Elliptical horn with any required mouth aspect ratio. Horn.e.lla automatically generates a database where records all routed designs and from where it is possible to recall the designs. The saved files are 2D and 3D x,y,z points ready to import into your CAD software with which to create the mechanical parts of your horn.

Sicer pa, kaj pravi moj dober prijatelj o hornih:

"Usually with horns, a certain unwritten law is always violated, to wit: thou shall NOT get the acoustical gain on the other side of the diaphragm. To the extent that a horn IS a horn, it is a selective frequency transformer, with multiple reflections in the horn aperture, and variable frequency gain, or to put it more classically, variable impedance match to the air load.

But horn designers never give up, and keep playing with these thousands of years old designs. Did you know that in outdoor Greek theater, the actors wore masks which incorporated short horns tuned to their speaking voices? These horn/masks were called PERSONAS. Speaker theory just doesn't get any older than that. The Greeks and Romans also used very large urns of stage, several meters tall, which functioned as acoustical resonators, amplifying lower frequency sounds."

"Higher Order Mode, its a term that I coined to define waves that propagate in a waveguide that do not go down the axis, but travel by bouncing off of the walls. They are not predicted by the Horn Equation, so most people didn't even know that they existed (I was the first person to hypothesize there existance). The Waveguide Theory predicts them, and low and behold, it turns out that they are quite significant to audibility. Minimizing them yields a far better sound quality. But with "horns" its not possible to minimize them because you don't know what to do - the equations aren't rigorous enough to predict them so they are simply ignored."

The five-way Incubus Club System unites the highest levels of performance ever achieved with the biggest leap in style consciousness since the invention of the loudspeaker, the company says.

The Incubus system incorporates the Air Array, Hyperfold, and Incubus subs.

The Air Array is the mid-high element of the club system delivering high-level, high-fidelity sound. The low mid-section of the Air Array consists of two hyperbolic horns fed from a split manifold driven from four 12'' transducers. Each 12" transducer also features a heat-sinking system to reinforce reliability and reduce power compression levels. Four devices that use a newly developed 3" exit compression driver handle the midrange frequencies. These devices make use of a 6" diaphragm to comfortably reproduce frequencies down to 500Hz with very low distortion levels. While the high frequency section is derived from six 35mm diaphragm, 1" compression drivers delivering frequencies above and beyond the normal scope of hearing, the company says.

The hyperfold 4 x 15'' upper bass enclosure is derived from the Void pyramid horn system. Originally incorporated for the Para flex 640 system, this new configuration radically increases the bass intensity to an unprecedented level, the company says.

Incubus subs sonically challenging design consists of three 21" transducers in a hybrid horn band-pass enclosure. A combined power handling of 6,000W rms and a very high sensitivity result in foundation cracking sub all the way down to 30Hz, shared the company.
